Do we need metamodels AND ontologies for engineering platforms?
In this paper we show how the joint use of metamodeling and ontologies allows to describe domain knowledge for a complex domain. Ontologies are used as stabilized descriptions of a business domain while metamodels allow a fine description of the domain (to be constructed in the initial phases of modeling). We propose to use an ontology for early categorization, i.e., as a "natural" complement of the formal system that is induced by the metamodel.
Development Platforms as a Niche for Software Companies in Open Source Software
As long as information systems do not become overly large and while they address a well-known domain, they can be controlled by engineering staff. Nevertheless, when dealing with large-scale, complex, or innovative information systems, it can be difficult to separate design issues and to formulate a meaningful information system proposal. In such a context, platforms for software engineering appear to be a promising approach. In this paper, we propose to view development platforms as a major opportunity for Open Source Software and Open Formats.
UML-Based Metamodeling for Information System Engineering and Evolution
In modelers’ practice metamodels have become the core of UML-based metamodeling environments: metamodels form the basis of application domain descriptions, and they are instantiated into models. In the context of information system engineering and interoperability, we have developped two operations on metamodels: metamodel integration and measure of semantical distance between metamodels. In this paper, we explore application of these operations to information systems’ evolution.
